INTERCHANG-EABLE NAME PLATE Application filed January 25, 1329. Serial No. 33%,917.

This invention relates to improvements in interchangeable letters or numbers which will 7 be visible through the windows, and will be protected from rain and other elements.

10 An object of the invention is to provide an improved name plate for use for ofiices, cabinet files, letter boxes, building directories and the like, which will be so arranged that interchangeable letters or numbers may be insorted within a channel in the plate behind transparent windows thereby displaying the desired indicia and at the same time protectingthe same from rain, dust and finger-prints.

A further object of the invention is to provide an improved interchangeable name plate which will be highly eflicient in use and quite inexpensive to manufacture.

Other objects will appear as the description proceeds. a

Drawings Description 'My improved interchangeable name plate comprises a casing 1, consisting of a pair of spaced reinforcing strips 2 secured 1n fixed relation by facing sheets 3 of celluloid, which are suitably afiixed at one or both sides of the said strips 2, thereby providing a longitudinally extending centrally disposed channel for the reception of the desired letters or numbers making up the preferred sign.

The celluloid sheets 3 are slit adjacent the oposite ends of the plate in line with the channel 4, and are bent outwardly to provide the guiding lips .5 to assist in the ready insertion oflthe letters or numbers 6 within the chan ne 4.

In making the desired sign,the casing 1 is supported in such a manner as to facilitate the positioning of the indicia. The letters or' numbers-6 are placed at one end of the channel 4 and are guided bythe lip 5 until they are supported in said channel. A filler strip 7 of substantially the same cross sectional area ofthe channel is then inserted in the channel after each letter 6 is placed in the end of the or; channel, and will be utilized to push the hum l bers to the desired position within the casing. After the sign is completed, a filler strip 7 will be inserted in each end of the channel until the channel is completely filled. The 0 outwardly extending portions of the'strips 7 l will then be filed ofi or otherwise separated to provide flush ends for the sign. 7

It will be understood that the sign can be provided with only one transparent window, .7

or with windows at opposite sides thereof as illustrated in the drawings, or can be molded from an integral piece of celluloid with trans.- parent windows.

If the celluloid becomes scratched, or vi-.80 sion through the same is impaired, the sign may be turned to the opposite side and the letters reversed, thereby giving a double life to the sign.

The letters or numbers in the letter blocks;

6 may be constructed to reflect light to add brilliance to the same, or they may be made luminous for viewing at night by the use of" radium paint.

Many minor changes in detail of construc-. tion may be resorted to without departure from the spirit of the invention. r

I claim:

1. An interchangeable name plate provided with spaced reinforcing strips forming a longitudinally extending centrally disposed channel, transparent celluloid sheets secured to said strips at the opposite sides thereof to provide a substantially rigid casing having oppositely disposed windows, outwardly i turned guide lips formed in the sheets at the ends of said channel, and adapted to receive a plurality of interchangeable letters in said channel. v

2. An interchangeable name plate provided with spaced reinforcing strips forming a. lon- I gitudinally extending centrally disposed channel, transparent celluloid sheets secured to said strips at the opposite sides thereof to provide a substantially rigid'casing having oppositely disposed 'WindoWs, outwardly turned guide lips formed in the sheets at the ends of said channel, and a plurality of inter changeable letters receivedin saidzchannel.

3. An interchangeable name plate provided with spaced reinforcing strips forming a longitudinally extending centrally disposed channel, transparent celluloid sheets secured to said strips at the opposite sides thereof to provide a substantially rigid casing-having oppositely disposed windows, outwardly turned guide lips formed in the sheets at the ends of said channel, a plurality ofinterchangeable radiant letters received in said channel, and filler strips insertable in said channel at the opposite ends of said letters and extending flush With said casing.
